This paper proposes a 0.18um CMOS vision sensor that combines event driven asynchronous readout of temporal contrast with synchronous frame-based active pixel sensor readout of intensity. The sensor is suitable for mobile applications because it allows low latency at low data rate and therefore, low system-level power consumption. The image frames can be used for scene analysis and the temporal contrast events with 12us latency can be used to track fast moving objects. © 2013 JSAP.
